Anterior to psoas fusion: Radiological parameters and associated clinical outcomes

Abstract

Anterior-to-psoas (ATP) or Oblique Lumber Interbody Fusion (OLIF) procedures have gained popularity, resulting in an increasing number of studies reporting associated outcomes. Analysing these outcomes is crucial for understanding the procedure's benefits and limitations. This review identifies commonly reported radiological parameters, including indirect decompression, fusion rates, subsidence, spondylolisthesis reduction, and deformity correction. By evaluating existing literature, we provide a commentary on these parameters and their impact on clinical outcomes. This review serves as a valuable resource for surgeons, aiding in patient evaluation, surgical planning, informed consent, and technical execution of the procedure.
